The Schedule referred to in these Letters Patent and making part of the same.

To `all whom 'it may concern Be it known that I, G. H. KAMNGHER, of Co-v lumbus, in the county of Franklin, and State of Ohio, have invented a new and improved Hoisting-Apparaenable others skilled in the art to make and use the saine, reference being had to the accompanying drawrlhe object of this invention is'to provide a cheap and simple portable hoisting-apparatus, foil bricklayers and builders, for hoisting the bnildingrlnaterial.

The invention consists in the arrangement on a bench or horse,' of a large grooved hoisting-wheel, a pair of balancingfplatforlns, vertical guides for the saine, and hoisting-ropes, all as hereinafter more fully Figure 1 represents ,a front elevation, and Figure 2 represents a side elevation of my improved apparatus.

Similar letters of reference indicate corresponding parts.' A represents a common bricklayers bench or horse, provided with a long vertical opening'throngh the beam. B represents a large grocved chain-wheel, mounted with the said bench.

C represents vertical ways, connected to near the centre; and

D, similar ways, either connected to the bench or the tenen E represents plat-forms, suspended from cross-heads F, and tted as the cross-heads, also, are to slide up and down on the ways C D. connected to a chain, G, passing over the wheel B, whereby the platforms balance each other thereon.

Ropes or chains H are connected to the bottoms of these platforms, for drawing them down, and they are carried, for convenience, under guiding-rollers I. The drawing of one carriage down elevates the other.

K represents catches, for holding theloaded platforms up until unloaded.

This apparatus is,very simple, and may be readily put into place upon the floor of buildings being built; transferring frein one to the other, as new floors are added, by raising the bench and lengthening the chain G and the guides C D, which consist of thin strips of wood. A

The bricks, incita-r, and other substance to be elevated, may be wheeled on to the platforms in wheel-bar-l rows, or be placed thereon in any other convenient way.

Having thus described my invention,

I claim as new, and desire to secure by Lett-ers Patent- The combination, with a chain-wheel, or chain, and
